How To Build A Catapult

table top troll catapult logo

This is a tiny replica of the massive siege engines that were used to tear down castle walls in the Middle Ages. You can make one of these catapults with just a few pieces of wood and a little bit of know how. I will guide you through the whole process. There are lots of different ways to power up a catapult and the way I show you in this tutorial is probably the easiest - you need just a rubber band or two.


Build the Table-Top Troll Catapult. This is a great little siege engine that really hurls projectiles! You just need some wood, a few screws, a rubber band and a couple of hours. This little catapult really hurls projectiles. And you can really tweak it to be quite a powerful little troll.

This tutorial on how to build a catapult takes you through all the steps in showing you how to do it. Want to see it in action? Here is a quicktime video of this catapult in action - Table Top Troll Catapult video.


Note From Will: If you are looking to buy a Siege Engine kit that you can make yourself you should check out my siege engine store. I have all kinds of trebuchets, catapults and more all available from Amazon.com - The Siege Engine Store

The Table Top Troll Catapult

What do you need to build this catapult?

Parts list for the catapultParts List: You don't need a whole lot of parts or tools to make this catapult and this is just a suggested list and these are the parts I use to make the catapult in this tutorial. You can fudge and replace lots of the parts. If you are creative there is a whole host of parts and things you could use instead of these parts. As you can see though it is pretty basic and you don't need a lot to build a basic catapult.



parts in the picture:

  • 3 pieces of wood 12 inches long
  • 8 pieces of wood 6 inches long ( two of these pieces have the ends cut at 45 degree angles - I will explain more about these.
  • An assortment of small screws and/or nails
  • 1 large rubber band or several smaller ones
  • 2 eye hooks (to the right of the rubber band
  • Some glue (optional but a good idea)
  • 1 four inch square piece of cardboard or poster board (This is the basket that your projectile sits in
  • 1 metal bar at least 6 inches long, I am using the axle from an old toy car (thats the wheels)

the catapult pivot About the metal bar from the axle: This is what I am using but you can use almost anything similar. This is going to be the pivot point for the catapult arm so you need something thin and strong. Here are some suggested things you could use: very firm coathanger wire - the cut off blade of a screwdriver, the metal bar handle from a bucket. Take a look at the close up of the catapult arm pivot on the left. See how it is going to be installed. So think of this and find some kind of metal bar for this. If all else fails you could even use a pencil or a pen. You would just have to drill a hole large enough for it to pass through. I used the axle from a toy car which works perfectly. So you may want to scrounge through your toy box to find one.

That's pretty much everything unless you want to paint and decorate your catapult. So lets start on the tutorial and make one ourselves!

Let's Begin building our Catapult !


Can you build a catapult like the Table Top Troll? You sure can. This is the pinkpult! Made as a father and daughter project!" It came out great and my thanks to them for sending in the picture!"









Want to Build a Bigger Catapult? I also have this project:

The backyard Ogre CatapultThe Backyard OGRE Catapult

This is a powerful two foot long catapult. I have complete instructions and tutorial on how to build it here The OGRE




The Wyvern Catapult

The Wyvern Torsion catapult
Complete project with step by step assembly instructions, blueprints and a video for making this powerful 3 foot catapult. It uses twisted rope for torsion. This type of catapult is called a Mangonel.The Wyvern Catapult





Torsion powered mangonelNew Catapult Project The Torsion Powered Mangonel. A mangonel is a type of catapult that is true to the real catapults they made in the Middle Ages and Medieval Times because they didn't have rubber bands! They used twisted rope for power and this table top Mangonel does the same. It is more historically accurate. It is also easy to build and pretty powerful for such a little catapult. How to build the Torsion Powered Mangonel Catapult


So how far does this torsion catapult fire? I show you by firing it off and use a measuring tape. I also give you tips and tricks for making your catapult even better. This includes a video that shows everything. Firing Off a Catapult

Office Supply Catapult

Office Supply Catapult - Here is a wonderful catapult built totally out of office supplies! It was made by Brandon N. And he used rubber bands, pencils and a few other things from around the office. It has a range of about 15 feet and that can be extended with the use of more rubber bands. See more pics and see his office supply trebuchet too. The Office Supply Catapult



Mouse Trap Catapult

New Project: How to make a Mouse trap Catapult in about 1 minute. You don't need much and this thing is really powerful. You can probably fire small projectiles about 40 feet. How to make a Mouse Trap catapult



If you are looking for something easier to make you might want to try my project on making a popsicle stick catapult. Fast, easy and fun project! Goes great with the paper medieval castle. Make a popsicle stick catapult





Can you make one of these catapults? You sure can and here are some pictures submitted by a web visitor who made one! It came out great and he made a modified release mechanism. This was done by Brendan H. (Thanks Brendan!) Brendan's Torsion Powered Catapult (Mangonel) This is based on my Torsion powered Mangonel Catapult project here

The Easy catapult. This is a great example of making a catapult without using any nails or glue and creating a neat little catapult to have fun with! The Easy Catapult

Another Interesting Project: How to Build a Trebuchet

Make a trebuchetThe Trebuchet was a unique siege engine of the middle ages. It was extraordinarily powerful and was easier for military engineers to build because it used gravity as the energy source. I also have a complete project on how to make the Little Dragon Trebuchet.
